Now that APG 3 is in alpha I had some time with the preview function. Great change in my workflow. I can now really prepare everything interactively and have the system render only once for a perfect result. Als rendering runs when I am away from the computer, there is not need to be really fast.

However, doing things more interactively by using the preview also means waiting a lot for the preview to finish. As I understand it, the preview uses the GPU a lot.. I know I have only a simple one an ATI RADEON HD 4600 series. I am willing to replace it if is speeds up the interactive part of the proces.

Any ideas for a good GPU that works great with AGP 3.0?

I'm not sure how much a "better" GPU helps the AGP3.0.0 preview. I have a GTX570 and previews are OK but not that fast. GPU utilisation is never above 5% and my GPU monitor shows not a lot of the processing engines are being utilised.

I've 1GB of VRAM which is fairly typical. I wonder whether the system is constrained by CPU/GPU memory bandwidth... I've had this experience with other imaging apps that leverage GPU's.

it opccurs to me I should run some tests with GPU disabled to see how 12core CPU @ 4.2GHz does in comparison. I'm not complaining about performance, I just note a pretty ordinary GPU is not the obvious constraint on speed....

In case you work with MSWindows what programm do you use to tell you the GPU %

kind regards,

Hans

Finally installed a PCIe SSD, the revodrive3 with 111 GB. Instead of having pagefile and first tempdirectories on a sata-ssd they are now on the PCIe-SSD

First impressions are very possitive, rendering time is almost half and machine feels more responsive, with less "almost hanging" where I have to wait for the machine to respond to me.Further testing to be done but this was 212 euro very well spend. Working on a 70 panorama project it will earn itself back in no time.

yes you can boot from them, but I did not install it as such as I don't see the point of waisting that space on OS. OS when it is running does not need a lot of I/O

Experience since friday evening is that my CPU is hitting 100% more often and for longer periods. Disk I/O looks like doubled and rendering time 50% of what it was. I think we have ourselve a no brainer here : if you can't expand memory anymore and CPU is not often close to 100%, have a look at PCEi-SSD's for tempfiles and pagefile

So from your first ! I can conclude you agree it is not a bad deal and for that price worth to try and see if it works? If not, only 85 euro gone ;-)

yes only for preview but that is when I am behind the computer. Other tasks are done while I am away and are allowed to be slow.

For 85 euro it is worth the gamble and if it works others will profit from this knowledge.

Nice to know that though you have a big machine you can still appreciate the small things in (computer)life ;-)

Hihi, I hope you saw the smiley ;-) Your confirmation is much appreciated at this side.

Oeps......installed the card, it has OpenGL according to GPU-Z but.... o well, was worth to try

anyone any ideas

... and did you install some drivers too ?(Im using a quiet old NVIDEA GTX260 and working nearly perfect - just not using the most recent drivers - just the second newest driver does work... so I think all 1-3 years old NVIDEA's finally should work...)Georg

A restart after lot of installing did the trick. Things seem to work fine. Not so much faster but I am now able to have two editors open and switch to the other while one is rendering its preview.....nice.

Absolutely. this seems like a cheap way to get a card with some GB's and decent performance.

Doing 48 RAW files per pano, I can now do most of editing and correction of about 4 to 5 panorama's an hour. That is of course without loading, detection and rendering. 15 minutes per pano spent behind the computer is much better then it used to be :-) It used to be that I just did not use the GPU...

Below is a picture of my screen while preview rendering two panoramas. The GPU memory is well used, the GPU itself not as much as I hoped for. maybe it is because lots of data still needs to be loaded from the temp-directories into GPU memory. Hard to say where the bottleneck is now.In the resource monitor the processes are sorted from high % to low, the disk I/O from hight total bytes to low. Pagefile is rarely going over 10 MB/sec so not really high. Actually during editing or rendering for preview none of the normal indicators seem to go up very high...are there tools to find out about other botlenecks...
